Prisoner On The Hell Planet
What Are Planets Made Of?
The inner planets, Mercury, Venus, Earth and Mars, are made upward of silicate stone and heavy metals such every bit atomic number 26 and nickel, whereas the outer planets, Jupiter, Saturn, Uranus and Neptune, are made up mostly of gases, according to Universe Today. The outer planets are subdivided into gas giants, comprised generally of hydrogen and helium, and ice giants, comprised more often than not of methane, ammonia and water.
Despite being made upwards mostly of gases, the outer planets have a rock core. Even so, they are still less dense and located further away from the sun than the inner or terrestrial planets. Astronomers are able to to determine how planets formed past studying the structure of the solar system and other younger planetary systems that are in varying stages of development.
The dominant theory, according to HowStuffWorks, states that solar wind emanating from the dominicus blew light elements, mostly gases, away into the outer orbits. Gravity then drew these elements in causing them to form behemothic balls. The discovery of hot Jupiters in 1995, nevertheless, put a dent in this theory. Hot Jupiters are a type of gas giant that orbit very close to the sun. Astronomers conjecture that such planets course far away from the lord's day and so motility closer through orbital migration.
